Negative-Sequence Current Injection of Transmission Solar Farms
IEEE Transactions on Power Delivery, 2020Integrating solar generation brings about unique challenges in power system protection. Previous studies have found inverter-based resources featuring distinct fault responses compared to conventional generators. The reduction in fault current magnitude and lack of negative and zero sequence currents can fundamentally impact the way that the power ...

Impact of negative sequence current injection by wind power plants
2013 IEEE Power & Energy Society General Meeting, 2013This paper presents an analysis of the impact from negative sequence current injection by wind power plants in power systems under steady-state and short-term unbalanced conditions, including faults. The separate positive and negative sequence current control capability of the grid-side converters of full scale converter type wind turbines may be ...

Negative-Sequence Current Injection for Fast Islanding Detection of a Distributed Resource Unit
IEEE Transactions on Power Electronics, 2008This paper presents an active islanding detection method for a distributed resource (DR) unit which is coupled to a utility grid through a three-phase voltage-sourced converter (VSC). The method is based on injecting a negative-sequence current through the VSC controller and detecting and quantifying the corresponding negative-sequence voltage at the ...

DC voltage balance based on zero sequence voltage is commonly used for star-connected cascaded H-Bridge (SCHB) STATCOM to compensate negative sequence current. However, zero sequence voltage injection brings about side-effect of increasing STATCOM output voltage and thus the Negative sequence Current Compensation Range (NCCR) is significantly limited ...

Grid Support During Asymmetrical Faults using Negative Sequence Current Injection
2019 IEEE 4th International Future Energy Electronics Conference (IFEEC), 2019This paper investigates the effect of injecting negative sequence reactive current into the grid in case of asymmetrical faults. In such conditions, the negative sequence voltage will increase and may cause instability in the system or damage to some equipment such as three phase rotating machines. Hence, the aim of this study is to support the grid by

Cascaded H-bridge STATCOM is widely adopted to regulate the power quality in power grid and industrial application. Considering the existence of zero-sequence voltage which cannot be neglected in the simulation model, this paper proposed an improved clustered voltage balancing strategy based on negative-sequence current injection.
